Step-by-step explanation:
In a particular region, for families with a combined income of $57,000 or more, 12% have no children, 37% have one child, 43% have two children, and 8% have three children. Use this information to construct the probability distribution for X, where x represents the number of children per family for this income group. Arrange x in increasing order and write the probabilities P(x) as decimals.
Answer:
P(X = 0) = 0.12.
P(X = 1) = 0.37.
P(X = 2) = 0.43.
P(X = 3) = 0.08
Step-by-step explanation:
12% have no children
This means that P(X = 0) = 0.12.
37% have one child
This means that P(X = 1) = 0.37.
43% have two children
This means that P(X = 2) = 0.43.
8% have three children.
This means that P(X = 3) = 0.08

The length of a diagonal of a square is 18√2 inches. Find the perimeter of the square.
A diagonal of a square is defined, [tex]d=a\sqrt{2}[/tex] where a is side of the square. Solve for a to get [tex]a=\frac{d}{\sqrt{2}}[/tex].
Now multiply a by 4 since that is the definition of a perimeter,
[tex]P=4a=4\cdot\frac{18\sqrt{2}}{\sqrt{2}}=4\cdot18=\boxed{72}[/tex].
Hope this helps.

Answer: See explanation
Step-by-step explanation:
ΔLNM and ΔLKN are 30°- 60°- 90° triangles
We have to find the length of LN before we can find the length of MN.
In a 30°- 60°- 90° triangle, the length of the hypotenuse is 2 times the length of the shorter leg, and the length of the longer leg is the length of the shorter leg times √3
Since the hypotenuse is 6, the short leg would be 3 since the hypotenuse is 2 times the length of the short leg.
LN = √3 times the shorter leg
3 × √3 = 3√3
LN = 3√3
We now know the length of the longer leg in ΔLNM (3√3)
MN would be 3√3 × √3
3√3 × √3
= 3√9
= 3 × 3 = 9
MN = 9
ΔLKM is also a 30° - 60° - 90° triangle
The short leg is 6 m
The hypotenuse would be 12 m
The longer leg would be 6√3
Perimeter: 6 + 12 + 6√3
The perimeter is 18 + 6√3
Area: 1/2 × b × h
b = 6√3
h = LN = 3√3
6√3 × 3√3
18√9 = 18 × 3 = 54
Area: 54 m²

A)5 ft
B)25 ft
C)81 ft
D)128 ft
Answer:
A) c = 5 ft
Step-by-step explanation:
a = 3
b = 4
3^2+4^2 = c^2
c^2 = 9+26 = 25
c = 5
Answer:
B
Step-by-step explanation:
Unfortunately, I dont really have a explanation for this besides yellow square is larger than both red and green, so using judging by the answers, it has to be B.
Which lines are parallel to 8x + 2y = 7? Select all that apply.
Answer:
9x+2y=7 hear something
Step-by-step explanation:
for each sequence find the first 4 terms and the 10th term
Answer:For these, n is equal to the term you want. So you substitute the number in for whichever term you want. This means:
a) 1 (1st term) + 5 = 6
2 (2nd term) + 5 = 7
3 (3rd term) + 5 = 8
4 (4th term) + 5 = 9
10 (10th term) + 5 = 15
And so on for b (not going to keep writing the term, I’m sure you get that by now.
b) 2(1) - 1 = (2x1) - 1 = 1
2(2) - 1 = (2x2) - 1 = 3
2(3) - 1 = (2x3) - 1 = 5
2(4) - 1 = (2x4) - 1 = 7
2(10) - 1 = (2x10) - 1 = 19
Hope this helps :)

Find x. Round to the nearest tenth.
4
6
5
Answer:
7.5
Step-by-step explanation:
The ratio between the two numbers in each set are the same, so the process used to get from 4 to 6 could also be used to find x. 6/4=1.5, so 4*1.5=6. Multiplying 5 by 1.5 would get x. 5*1.5=7.5, so x=7.5.

Fill in the missing number to complete the equivalent fraction show what you multiply or divided by convert each improper fraction to a mixed number or whole number
Answer:
3a) 5/45 you divide by 5
3b) 6/7 you divide by 2
3c) 2/7 you divide by 9
3d) 2/5 you divide by 9
4a) 6
4b) 1 1/4 or 5/4 (both are correct)
4c) 3 1/2 or 3 3/6 (both are correct)
4d) 5 1/8
The fraction bar tells you to divide the top number by the bottom number.
Step-by-step explanation:
For 3a through 3d, you just use the fraction that has a missing number, and if the missing number is at the bottom, use the top number and devide it by the other top number that the fraection is equal to.
For 4a through 4b, devide the top the bottom number
If 120 L of an acid solution is 75% acid, how much pure acid is there
in the mixture?
Answer:
25% or 30L
Step-by-step explanation:
100% is 120L, we know 75% is acid, we need the other 25% to make the 100%. 25% of 120 is 30, so 30 liters is pure acid
the difference between two numbers is 308 328. if the smaller number is 6 524, what is the larger number?
The larger number is 301804
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given;
The smaller number =6 524,
The difference between two numbers = 308 328
Now,
Let the missing number be x
x-6524=308328
x=308328-6524
x=301804
Therefore, the larger number of algebra will be 301804.
